Best=what you'll do!:
Yes, endurance/other activity that raises hr is better than simply lifting weights, eg. But the regimen need not be overly strenuous. Even walking has been shown to have beneficial effects on cognitive function of "seniors" (note the numerous articles by art kramer, phd, and colleagues). So it is best to select or continue an activity that is enjoyable and engage in it on a regular basis.

Str vs Endur:
Strength is looking for maximum output over a short period of time. An example of this would be powerlifting. Endurance would be training for long periods of time usually at a reduced rate. This would be a distance runner. Usually it is best to cross train, or train for both as in doing so you can develop both types of muscle fibers, fast twitch (strength) and slow twitch (endurance).

Most men are done with vertical growth by about 20..Some may stop a bit earlier and some later, but my guess would be around 20. Unfortunately, we continue to grow sideway persistently into oldage. If stretching can increase height, i would be doing it every day.

No:
I know of nothing that will increase your height. Very rarely people do grow a bit in height after 21, but over 99% of the time one has stopped growing by age 21 & i know of nothing that will change that.While not as tall as average (average height in the us for caucasians is about 5'10", but 5'7" for hispanics) you are not unusually short. Given this is unlikely to change, it is wise to accept it.

See below:
Decrease processed carbohydrates, such as bread, pasta, cookies, and so on. Eat well balanced meals, including healthy carbs, fats, and proteins. Drink water.
Do weight intensive exercises with your major muscles, working to do each set to exhaustion. One or two sets, six to eight reps each, once or twice a week, so show excellent results in two months. You may not be using heavy enough weights.
